The invention relates to a new and improved window having pivotallymounted tracks for guiding the upper and lower sashes, said sashes beingremovable from their guiding means when said tracks are swung out of theplane of the frame.

One object of the invention is to provide a window of the class setforth which may be constructed with fewer parts and hence atconsiderably less expense than the conventional window, the simplifiedand cheapened structure however, being nevertheless greatlyadvantageous.

A further object of the invention is to provide resilient means whichperforms the two-fold function of holding the sashes in adjustedposition when slid along the tracks, and pressing said tracks againstthe stiles of the window frame, with sufficient friction to hold saidtracks when they are swung about their pivots.

Another object is to provide novel releasable means for normally holdingthe sash-guiding tracks in vertical position.

Yet another aim is to provide for quick and easy detachment of thesash-guiding tracks when the window frame is to be painted.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, description being accomplishedby reference to the accompanying drawings.

Fig. 1 is a vertical sectional view with the sashes removed, thesash-guiding tracks being shown in vertical position in full lines andswung inwardly in dotted lines.

Fig. 2 is a View similar to Fig. 1 but showing the sashes andillustrating the lower sash partly raised.

Figs. 3 and 4 are detail horizontal sectional views on lines 3-3 and 4-4of Fig. 2.

Fig. 5 is a detail vertical section on line 5-5 of Fig. 2.

Fig. 6 is an enlarged detail View showing the pivotal mounting for oneof the upper sash-guiding tracks.

Fig. 7 is a View similar to Fig. 6 but showing the manner of detachingor attaching the sashguiding track with respect to the pivot.

Fig. 8 is a detail horizontal section on line 8--8 of Fig. 6.

Figs. 9 and 10 are edge views of two different forms of sash-holdingsprings.

In the drawings above briefly described, the numeral 10 denotes a windowframe whose stiles 1l are provided with flat parallel inner sides, saidStiles being secured in any suitable way to a header 12 and a sill 13.

Two sash-guiding tracks 14 lie against the lat inner sides or" thestiles 11 and extend throughout the lengths of the upper halves of saidstiles. rwo similaisash-guiding tracks 14=L lie against the inner sidesof the stiles 11 and extend 60 throughout the lengths or' the lowerhalves of said Stiles, the meeting ends of the two sets of tracks beingbeveled as denoted at 15. The upper ends of the upper tracks 14 arepivoted at 16 to the stiles 11, and the lower ends of the lower tracks14a are similarly pivoted at 16a to said stiles.

An upper sash 17 is slidably engaged with the upper tracks 14, and alower sash 17a is similarly engaged with the tracks 14a, and theadjacent ends of these sashes overlap in the usual manner and may belocked together by a conventional sash fastener. To hold the sashes 17and 11a in adjusted position and to frictionally hold the tracks 14against the inner sides of the stiles 11, I provide any desired numberof springs which exert an inward pressure on the sashes and an outwardpressure on said tracks. In the present showing, two bowed springs 18are spot-welded at 19 to the inner sides of the tracks 14, and twoadditional springs 18CL are welded at 19a to the inner sides of thetracks 14a. These springs bear frictionally against the vertical edgesof the sashes and thus serve to hold the latter when they are slid toany desired position. Then too, when tracks and sashes are swunginwardly about the pivots 16 and 16a, the springs 1S and 18ad press saidtracks against the stiles 11 with sufficient friction to hold saidtracks in the positions to which they have been swung. When either sashand the associated tracks are inwardly swung, the sash may be entirelyremoved from engagement with said tracks for quick and easy cleaning,and said sash may be easily re-engaged with said tracks. The swingingand sliding of the sashes is also of advantage for Ventilating purposes.

Each of the tracks 14 and 14a is preferably formed from a singlevertically elongated strip either stamped or cast to provide it withparallel sash guides, the guides of the upper strip being denoted at 20and 20', and those of the lower strip at 2l and 21. The outer edges ofthe tracks or strips 14 and 14a preferably abut shoulders 22 on thestiles 11, when in Vertical position. At this time, the upper ends ofthe tracks 14 preferably abut the header 10 and the lower ends of thetracks 14a similarly abut the sill 13.

In order to prevent the tracks 14 and 14e from dragging excessively uponthe inner sides of the stiles 11 when they are swung about their pivots,I preferably inset wear plates 23 in said stiles, the track-engagingfaces of said plates being a few thousandths of an inch inward of theinner sides of said stiles. Both of these wear plates carry upper andlower spring tongues 24 and 25 stamped therefrom to hold the tracks 14and 14a normally in vertical position by abutting the inner edges ofsaid tracks. Pressing the tongues outwardly, releases the tracks forinward swinging.

To limit the swinging of the tracks 14 and 14, under ordinarycircumstances, I preferably provide them with arcuate slots 26 and 26CLwhich are concentric with the pivots 16 and 16a respectively, said slotsreceiving stops 27 and 27at carried by the stiles 11. When the sashesare slid from the tracks however, the latter may be sprung free of thestops 27 and 2'7a and then swung to horizontal positions, and the pivots16 and 16a are so constructed as to then allow detachment of the tracksto give access to the frame stiles for painting. In `forming each ofthese pivots, a short corrugated tube 29 is driven tightly into anopening in the frame stile, said tube having an elongated head 30 on itsouter end, passable through a slot 31 in the sash-guiding track andnormally extending across said slot. Sufficient swinging of. the trackhowever, so aligns the head and slot as to allow each detachment orattachment of said track.

In Fig. 9, I illustrate a slightly different spring 28 which may be usedin place of the springs 18 and 18a. Also in Fig. 10, I illustrate athird type of spring having two bowed portions 28a, this type beingparticularly adaptable to use with heavy sashes.

It will be seen from the foregoing that novel and advantageous provisionhas been made for carrying out the objects of the invention, and whilethe structure shown is preferably followed, variations may, of course,be made within the scope of the invention as claimed.
